· Mo4 S4 Te4

Mo₄S₄Te₄ is a mixed-chalcogenide semiconductor compound combining molybdenum with sulfur and tellurium in a layered structure. This is primarily a research material being investigated for its electronic and photonic properties, particularly within the broader family of transition metal chalcogenides that show promise for next-generation optoelectronic and energy conversion applications. The combination of sulfur and tellurium allows tuning of bandgap and carrier mobility compared to binary MoS₂ or MoTe₂ systems, making it of interest to researchers exploring two-dimensional materials and heterostructures for photovoltaics, photodetectors, and potential quantum applications.
